Age-related change in executive function: Developmental trends and a latent variable analysis
Genome-wide association analyses identify 44 risk variants and refine the genetic architecture of major depression
A genome-wide association meta-analysis of individuals with clinically assessed or self-reported depression identifies 44 independent and significant loci and finds important relationships of genetic risk for major depression with educational attainment, body mass, and schizophrenia.
Severity Indices of Personality Problems (SIPP-118): development, factor structure, reliability, and validity.
The final instrument, the SIPP-118, provides a set of 5 reliable, valid, and efficient indices of the core components of (mal)adaptive personality functioning, suggesting that the domain scores are stable over a time interval of 14-21 days in a student sample but are sensitive to change over a 2-year follow-up interval in a treated patient population.

A new explanation of the positive manifold based on a dynamical model is proposed, in which reciprocal causation or mutualism plays a central role, and it is shown that thepositive manifold emerges purely by positive beneficial interactions between cognitive processes during development.
Factor analysis of variables with 2, 3, 5, and 7 response categories: A comparison of categorical variable estimators using simulated data
- C. Dolan

Two estimators in the factor analysis of categorical items are studied, the weighted least squares function implemented in the tandem PRELIS-LISREL 7 and a generalized least squares function…
TATES: Efficient Multivariate Genotype-Phenotype Analysis for Genome-Wide Association Studies
TATES constitutes a powerful new multivariate strategy that allows researchers to identify novel causal variants, while the complexity of traits is no longer a limiting factor.

The factors affecting the type I error rate and the statistical power in nested data, methods that accommodate dependency between observations and ways to determine the optimal study design when data are nested are discussed.
